The goal of this program is to develop a concept for an optical computer for symbolic computing by defining a computational model of a high level language, examining the possible devices for the ultimate construction of a processor, and by defining the required optical operations. The efforts in this quarter were in the design and analysis of electronic shuffle-exchange networks (SENs), the identification of the bottlenecks in the performance of the network, and the subsequent determination of the guidelines for implementing an optical SEN such that optics can address the electronic limitations and provide the capability of designing a high-performance network. The analysis of electronic SENs required designing the interface between the processors and the SEN, the smart exchange within the board. We considered both gallium arsenide and ECL technologies to determine the highest performance of an electronic SEN. Keywords: Electrooptics.
